Substance use stigma reduces trust and informational support: experimental evidence across risk and relationship contexts.
Article in Harm reduction journal, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundThis study investigates the impact of addiction history on interpersonal trust and access to social support. Specifically, it explores whether people exhibit decreased trust toward individuals with addiction histories, explores the extent to which positive portrayals can mitigate such distrust, and evaluates whether those with addiction histories receive reduced social support from their closest social networks, including friends and family.
methodsTwo complementary studies were conducted. Study 1 employed hypothetical scenarios to assess trust in both property-related and personal risk situations and examined whether counter-stereotypical information could reduce distrust. Study 2 used vignettes depicting individuals seeking assistance in differing relational contexts (friends versus family) to evaluate responses and types of support provided. Ordinary Least Squares (OLS) regression was applied to estimate the effects of experimental manipulations on trust and social support.
resultsParticipants exhibited significantly reduced trust toward individuals with a history of substance abuse across both scenarios. Providing counter-stereotypical information significantly reduced distrust in the property risk scenario, but had no measurable effect on trust in personal risk contexts. Regarding social support, individuals with substance use histories received less informational support when assistance was requested by family members.
conclusionsThis research highlights the role of addiction stigma in shaping interpersonal dynamics, particularly in trust and social support. The findings suggest that targeted interventions addressing trust deficits, such as counter-stereotypical portrayals or trust-building programs, could play a role in reducing stigma and enhancing interpersonal relationships. Additionally, mentoring programs and improved access to informational resources may help bridge gaps in social support, especially where family support is limited. These insights have significant implications for rehabilitation programs, family support services, and community-based initiatives aimed at promoting successful recovery and reintegration.
